2017-12-21cli: Enable to filter EVPN routes by Route TypeIWASE Yusuke
Currently, "gobgp" command supports only to display all routes on RIBs, but with huge RIBs, it is convenient to select routes by a part of NLRI fields. This patch enables to filter routes by EVPN Route Type. For example, when 5 routes for each route type; $ gobgp global rib -a evpn Network Labels Next Hop AS_PATH Age Attrs *> [type:A-D][rd:65000:100][esi:single-homed][etag:10] [10] 0.0.0.0 00:01:09 [{Origin: ?}] *> [type:Prefix][rd:65000:100][etag:10][prefix:10.0.0.0/24] [0] 0.0.0.0 00:00:04 [{Origin: ?} [ESI: single-homed] [GW: 0.0.0.0]] *> [type:esi][rd:65000:100][esi:single-homed][ip:10.0.0.1] 0.0.0.0 00:00:19 [{Origin: ?}] *> [type:macadv][rd:65000:100][etag:10][mac:aa:bb:cc:dd:ee:ff][ip:10.0.0.1] [20,30] 0.0.0.0 00:00:54 [{Origin: ?} [ESI: single-homed]] *> [type:multicast][rd:65000:100][etag:10][ip:10.0.0.1] 0.0.0.0 00:00:33 [{Origin: ?}] You can select multicast route as following; $ gobgp global rib -a evpn multicast Network Labels Next Hop AS_PATH Age Attrs *> [type:multicast][rd:65000:100][etag:10][ip:10.0.0.1] 0.0.0.0 00:03:02 [{Origin: ?}] Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-12-20table: fix converting 2bytes to 4bytes AS PATHFUJITA Tomonori
On some conditions, we add some ASes to As4PathParam.AS but don't update As4PathParam.Num (the number of ASes). It breaks serialization of AS4PathParam. Instead of modifying the internal of As4PathParam, let's create a new As4PathParam object. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
2017-12-16table/policy: Support prefix representation in NeighborSetSatoshi Fujimoto
Currently, "neighbor-set" supports only IP address representation and IP prefix representation(such as "192.168.0.0/24") is not supported.

2017-11-24packet/bgp: Sort FlowSpec rules when decoding/creatingIWASE Yusuke
Currently, we sort the FlowSpec rules when creating a new path containing the FlowSpec NLRI and when parsing CLI arguments for the FlowSpec rules. This patch moves sorting the rules into the inside of the "packet" module and sorts them when decoding binary and creating new NLRI. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>

2017-08-07table: exclude mpreach and mpunreach attribute for normal v4 updatesWataru Ishida
It is possible that gobgp's v4 path structure contains mpreach or mpunreach attribute. (we store entire path attributes in path structure as they are received) Since we use a NLRI field of BGP update message for v4 updates and don't aggregate update/withdrawal messages for other address families, we need to exclude these attribute before sending out v4 updates.

2017-08-07table: fix handling of update with both mpunreach and mpreach attributeWataru Ishida

The local identifier for path is sent to remote peers. To simplify the implementation, 1) the local identifier is unique per prefix not peer. 2) always assign the local identifier even without addpath-rx-capable peer. In the future, we might need to improve 2) to avoid the unnecessary overhead. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>

2017-05-10table: Advertise local-pref set by import policyTatsushi Demachi
At importing a path from an external peer, LOCAL_PREF can be set by an import policy but at exporting a best path to an internal peer, this learned, calculated LOCAL_PREF is never used and every time overwritten by a default value 100. According to RFC 4271 "5.1.5. LOCAL_PREF" and "9.1.1. Phase 1: Calculation of Degree of Preference", the learned value should be advertised to other internal peers. This fixes it by just removing resetting a non-local path's LOCAL_PREF by the default value.
